Slice It However You’d Like

Option 1: Vase Mode (Spiral Mode)

Vase mode only really works for 1 bulb at a time. Just be sure to add 1-2mm of “bottom” layers so the tabs get printed with full thickness & strength.

Option 2: Slice It Fuzzy w/ Cura (<– do this)

I print an entire bed of these C9 diffusers overnight using the “Fuzzy” mode in Cura. Cura’s fuzzy mode hides the seams exceptionally well. (or so it…seams.)

Fuzzy Wuzzy Wuz A Cura Setting:

You may need to adjust your fuzzy settings to achieve the effect you like. Here are the settings to get the effect I like w/ PLA:

Fuzzy Skin: CHECK

Fuzzy Skin Thickness: 0.15mm

Fuzzy Skin Density: 1.25mm

Fuzzy Skin Point Distance: 0.8mm

and that’s how Fuzzy Wuzzy the Bear rolls at Christmastime.

What Material?

Shoot, that’s up to you! I’ve printed these in PET-G and PLA. After a year, both look great. But, mine haven’t been in direct sunlight. (in other words, I used PLA but don’t take my advice…. try for yourself and drop me a note if you find something you love or hate!)

What 3D Printer?

I don’t think it really matters for these puppies (puppies = a nickname for C9 diffusers), but I used my trusty Creality Ender 3 (typically in the $200 range). It is (and has been) my go-to printer for everything even though I have a bigger, newer printer.
